yeah i always thought it was where the us government did nuclear testing on things. like during the cold war and stuff. plus like i thought it was where the new weapons and stuff are popping up. thats your UFO theory right there.

Im a fan of the "if it looks like a duck, quacks like a duck, than its probably a duck"....meaning that it is what most people accept it for, an top secret airforce/military base, where R&D&T of highly advanced military aircraft takes place. It just makes to much sense for it not to be there....not to mention all the ufo sightings would certainly be explained by this.

Groom Lake Research Facility, AKA Area 51, is a top secret research facility in the Nevada desert.
Aliens? Possible. Aircraft and weapon research? Definitely.
A huge area of airspace around it is patrolled by fighters out of Nellis & according to stories I heard when I was in the AF, you REALLY don't want to cross that invisible line.
